主要功能
仪器轻便、操作简便、测量灵活
可以非破坏性的轻易获得冠层数字高精度图像
现场获取植物冠层彩色图像,并直接显示和储存到UMPC上
强大的冠层分析软件功能,可以手动调节阈值、自动调节阈值(OTSU)、光斑透过率Entropy三种冠层分析方法得到冠层参数
镜头自动水平,一次成像,测量不受天气、光线影响,无需天空空白对照测量
软件进行屏蔽、躲开影响图像计算结果的人影、天空等无用图像
测量参数
植物冠层叶面积指数(LAI)
叶片平均倾角(MLA)
散射辐射透过率(Transmission Coefficient)
消光系数(Extinction Coefficient)、直接辐射透过系数(Transmission Coefficient)、叶片分布(Leaf Distribution)
GPS定位信息(GPS Lock)
太阳光斑(Sunflecks)、光合有效辐射(PAR)
应用领域
植物冠层数字图像分析仪CI-110 用于各种高度植物冠层研究。利用鱼眼镜头和CCD图像传感器来获取植物冠层图像并进行分析。通过专业软件分析,获得植物冠层的相关指标参数;鱼眼镜头成像测量冠层数据只操作一次即可,简化了传统能量法要一天定点多次测量的繁复工作;图像法测量冠层可以主动避开不符合计算该冠层结构参数的冠层空隙部分,也可以躲开不符合测量计算的障碍物。
广泛应用农业科学、林木科学和植物结构分析等方面,研究植物叶面积指数与生产关系、林木的冠层指标、农作物和林木的生长监测;林木内的光合有效辐射强度;对不同纬度
